Problems solved by technology

[0003] At present, the operation status monitoring of power equipment mainly adopts the method of manual inspection and regular maintenance, which requires a lot of manpower, and requires the use of various test instruments to complete the detection and fault location of the equipment
In addition, manual inspection also has poor real-time performance, and it is not easy to find hidden defects in equipment in time

Abstract

The invention provides a power equipment monitoring system based on an infrared image. The system comprises an infrared image collection terminal which is used for automatically collecting infrared image data of power equipment, and transmitting the infrared image data to an image analysis platform through a mobile network; the image analysis platform which is used for receiving the infrared image data transmitted by the mobile network, identifying the power equipment through the infrared image data and determining the type of the equipment; and used for establishing a function relationship between an image gray value and an actual temperature by using a colorimetric strip and a temperature range thereof in the infrared image data, converting the image gray value into the actual temperature of the power equipment, selecting a preset fault temperature criterion according to the equipment type, judging whether the power equipment is in a normal operation state, and generating a judgment result; and an alarm unit which is used for determining whether the power equipment has a fault according to the judgment result, and if yes, displaying the fault type and giving an alarm. According to the invention, automatic identification and positioning and fault diagnosis of the power equipment can be rapidly realized.

Description

technical field [0001] The invention relates to the technical field of electric equipment monitoring, and more specifically relates to an infrared image-based electric equipment monitoring system and method. Background technique [0002] Power equipment is subjected to electrical, thermal, and mechanical loads during operation, as well as the influence of the natural environment (air temperature, air pressure, humidity, and pollution, etc.). Long-term work will cause aging, fatigue, and wear, resulting in gradual decline in performance and reliability. Gradually decreases. Under the long-term action of high voltage and high temperature, the insulating materials and conductive materials of the equipment will gradually lose their original working performance. As the operating period of the equipment increases, the performance and reliability gradually decline, and the failure rate of the equipment gradually increases, usually in the form of abnormal heating of the overall or ...
